ACE2 overexpression in colorectal cancer patients might increase susceptibility to SARS-CoV-2 infection. We report that knockdown, forced overexpression, and pharmacologic inhibition in human colon cancer cells targeted ACE2-BRD4 crosstalk to mediate marked changes in DNA damage/repair and apoptosis. In colorectal cancer patients for whom high ACE2 plus high BRD4 expression is predictive of poor survival, pan-BET inhibition would need to consider proviral/antiviral actions of different BET proteins during SARS-CoV-2 infection.
结直肠癌患者中血管紧张素转换酶2（ACE2）的过表达可能会增加对严重急性呼吸综合征冠状病毒2（SARS-CoV-2）感染的易感性。我们报告称，在人结肠癌细胞中进行基因敲低、强制过表达和药理学抑制，可靶向ACE2与含溴结构域蛋白4（BRD4）的相互作用，从而介导DNA损伤/修复和细胞凋亡的显著变化。在高ACE2加上高BRD4表达预示着生存不良的结直肠癌患者中，在SARS-CoV-2感染期间，泛BET抑制需要考虑不同BET蛋白的前病毒/抗病毒作用。
